None of my email messages will mark as read automatically (v 2.7.8039.0). Previous to this release they did. I have tried 1 second, 5 seconds and unticked without success. I have to manually mark each one as read. I read my mail as html and do no use the preview pane.
Disregard this question. After re-installing eM Client and re-updating to the newest version, this problem resolved.
Can I raise this question back up? I am running 2.7.8313.0. Like John, I open the emails and use the Previous button to navigate through them. But when I have finished reding them all, only the first and last are marked as read, the ones inbetween are Unread and I have to manually mark them as read.
